Pat Brower, the land committee chair for the Great Lakes Four Wheel Drive Association, said, "two-tracks are becoming an endangered species." Brower's group is for four-wheel-drive enthusiasts. Two-tracking is a favored pastime. He says the new maps will make for more confident decisions in the woods. But he thinks two-track opportunities are diminishing in federal forests. "They are getting caught in the pinch between urban sprawl and semi-primitive, non-motorized areas," Brower said.
